White ME30, ME40, ME50, ME30S, ME50B Parts Catalog – OEM Factory Manual

You’ve got a White ME30 or ME40 sitting in the shop with a dead traction motor, or maybe an ME50B that won’t steer. You pull up a third-party parts website, type in the model, and get back a list of generic numbers that don’t match anything on the truck. I’ve seen it happen a hundred times. That’s exactly why this White ME30, ME40, ME50, ME30S, ME50B Parts Catalog exists. It’s the actual factory document, 140 pages, printed from White Lift Trucks in Hopkins, Minnesota. Not a reprint, not a scan of a scan – this is the OEM file that dealers used to order parts for these electric forklifts.

Quick Reference Charts for Common Consumables

Flip to page 2 and you’ll find a dedicated quick-reference section that lists brushes, fuses, brake shoes, filter elements, and seal kits across all five models. The traction motor brush set (20-7301812) is listed for the ME30S through ME50. The lift and tilt motor brush set (20-7301998) covers a different group of models. If you guess, you’ll order the wrong one – I’ve watched guys do it, then spend an hour swapping it back out. That chart also gives you the fuse ratings: 400-amp bolt-in for the traction and pump motor, 30-amp for the power steering motor, 2-amp snap-in for the SCR 310 control panel. You need a 2-amp fuse? It’s right there.

What’s Missing from Aftermarket Catalogs?

Aftermarket parts catalogs love to give you a single part number for a “brush set” that supposedly fits everything from a 1972 Toyota to a 1995 Yale. They leave out the serial-number splits. This factory manual doesn’t. On page 1, the serial number ranges are printed: 51300001 for ME30, 51400001 for ME40, 51500001 for ME50, and 5310101 for the ME30S, 30H, 30HB, 40, 40B, 50, and 50B with SCR 310 or EV1 control. If you’re working on a late-model ME50B with silent drive transmission (serial 5310586 and after), the manual includes Supplement A with a new dipstick (20-3011627, 8-15/16 inches long) and tube (20-3011626, 7-1/4 inches). You won’t find that in a generic list.

3 Systems Where Exact Part Numbers Save Hours

Control valve seals (20-7301709) for the lift-tilt and auxiliary valve – aftermarket kits often leave out one o-ring. The tilt cylinder repair kit (20-7380008) – one number, one box, done. Power steering pump seal kits (20-7301677 or 20-7302210) depending on which pump model you have. Using the wrong kit means pulling the pump twice. With this catalog, you match the pump part number from the truck to the correct seal kit. Page 2 also lists the contact tips for the F&R contactors and hydraulic pump contactor – part numbers 20-7301773 for SCR 310, or 20-7302265 for EV1 control. If you’re retrofitting an EV1 panel, those numbers are different.

Parts Catalog vs Service Manual: Why You Need Both

This manual is a parts catalog, not a service or repair manual. It doesn’t tell you how to tear down the mast or rebuild the drive motor. What it does give you is the exact factory part number for every component, broken down by serial number. If you’re rebuilding a hydraulic pump and need the repair kit for pump 20-3005817, the part number is 20-7301267. That’s a fact. Pair it with the factory service manual (like the White ME30 service manual) and you’ll have both the procedure and the parts. No guessing which seal goes where.

White ME30S and ME50B: Special Considerations

The ME30S and ME50B share some drivetrain components, but the parts catalog keeps them separate. For the silent drive transmission introduced on ME30-55B after serial 5310586, you’ll find a dedicated gear reduction case (20-3011810), drive sprockets (49T output, 28T motor), and an endless chain (66 pitches, part 20-3011663). That chain is a pain to source if you don’t have the number. I’ve had guys show me a chain they ordered from a industrial supply house – wrong pitch, wrong length. This catalog kills that problem.

FAQ

How many pages does this manual have?

140 pages.

Does the parts catalog cover the silent drive transmission changes on later ME50B models?

Yes. The manual includes Supplement A with new parts for the silent drive transmission starting at serial 5310586 and after. It lists the reduction case, drive sprockets, and chain – part numbers 20-3011810, 20-3011812, 20-3011811, and 20-3011663. It also adds a revised dipstick and tube. If you’re working on a late-model electric White forklift, this covers the updates you need.

Don’t burn an afternoon chasing the wrong part number. This factory-published parts catalog gives you the OEM information White Lift Trucks used to support these models. The serial number breaks, the quick-reference charts, the seal and brush kit numbers – it’s all there in 140 pages. Access the Factory Manual and keep it on your bench next time you’re ordering parts for a White ME30, ME40, ME50, ME30S, or ME50B.
